Effect of a Static Dissipator Additive on the Charging Tendency of Jet Fuels

摘要

The effect of a static dissipator additive on the charging tendency of both JP-4 and JP-5 type jet fuels was examined at various flow velocities on a laboratory scale. For the document's use, the term 'charging tendency' refers to the current generated by a given quantity of fuel when passing through a filter or an insulated section of piping rather than to the ability of a fuel to produce dangerously high potentials when loaded into a tank. It was found that when the conductivity of the fuel is increased by the addition of the static dissipator additive, the charging tendency also increases, passes through a maximum, and then decreases. Also, at higher flow velocities, there is an overall increase in the charging tendency of the fuel, and the position of the maximum in the charging tendency vs conductivity curve shifts to a higher conductivity range.
